Marcellus Shale
The Marcellus Shale covers approximately 65 million acres or 2/3 of Pennsylvania and is located near the high demand marketplace of the Northeast. Pennsylvania has a long history of energy production. The first well within the U.S. was drilled in Pennsylvania in 1859 near Titusville. With the advent of horizontal drilling technology combined with modern hydraulic fracturing techniques, the Marcellus is now economically viable prompting recovery and marketing of its substantial resource of natural gas. Pennsylvania is no doubt being significantly affected by this development.
